Air tank pressure sensors
Does anyone happen to know the part number to the forward air tank pressure transmitter? Was getting ready to make a quick test run and the forward tank never indicates pressure.. verified was pressurized. My front connector is long enough to...

A quick search of the Forum archives did not turn up any part number for the transducers.  This might be a case where you will need assistance from the factory.  Try calling (or emailing) the FOT parts desk and see if they can give you a part number?

Scott, your coach has an electronic gray box from which the transducers get a source voltage and return a voltage based on resistance in the transducer and the pressure.  Somewhere in the gray box this is converted into an electrical signal used...

So suspected failed diaphragm in sender because on bench when pressurized then unpressurized would leak air out. Opened sender and verified bad diaphragm. Will replace both and keep old good one for a spare.

Received both senders in under 24 hour. Summit is outstanding. Installed both and verified normal operation of both systems. Pressure indication for both gauges increased 10 psi to 120psi. Both gauges move smoothly to max pressure without jumping...
